IMPROVEMEN'II IN WASHING-MACHINES.

I Specification forming part of Letters Patent No. 130,848, dated August 27, 1872.

i shallV be thoroughly cleansed. Third, so to construct a machine that, with the exception of the exterior frame or box, it shall be so put together, and its various parts so maintained in position, as notA to be liable to get out of repair, yet can be taken apart, cleaned, and adjusted without drawing nails or screws. Fourth, it.consists of vulcanized India-rubber and wooden rollers, rubber springs, metal concave frames or ribs, and metal sliding boxes, so combined as to produce the'foregoing results, which will be more fully shown i by the accompanying drawing.

y Figure 1 is top view of a machine embodying my invention. Fig. 2 is a door or system of' rollers with the frames or ribs detached in.

which they Work. Fig. 3 is a side view of the machine. Fig. 4 is a central longitudinal section of la machine when in working order,

showing the positions of the large and small y India-rubber rollers, the wooden rollers, the shape of the frames or ribs, and cushions or springs on which they frames or ribs rest.

Figs. 5, 6, 7, 8, 9, 10, and 11 are details of Fig. 4. Fig. 12 is a cross-section of a machine in Working order, showing the large roller in Vcontact with the small rollers beneath, and crank by which the former is revolved. Fig. 13 is an end view, showing the ends or ter- 'xninuses of the frames or ribs and cushions or sprin gs on which they rest.

General Description.

A A, Fig. 3, is the exterior frame of the machine, constructed Yof cheap, sound boards, dovetailed at the ends, the upper surface jstraight, about three feet long, about eight- `een inches wide, the lower surface concave in the direction of its length, with shoulders or extensions a a about six inches long in the same direction.- The depth of the frame at v at either corner, as shown in Fig. 3. C, Fig.

12, is the main roller, of straight surface, about seven inches in diameter, and, with the exception of a wooden center piece, hereafter described, is made` of vulcanized India rubber, a transverse section of which, c o, is seen in Fig. 4, and a longitudinal section c c in Fig. 10. Through the center of this roller, as above, passes a center piece of wood, c o', Figs. 4 and 10, for the purpose, and to either end of which are fastened gudgeons c, c" by means of the flanges b b, Fig. 10, on which the roller C is revolved by the crank D, as seen in Fig. 12. The gudgeons c c are elongated on the inside of the dan ges b b, and fitted into the sockets b b in the wooded center piece c c one-half or three-fourths of an inch, in order to preserve an exact central as well as rm motion tothe main roller C, Fig. 10, and in case of strong pressure to prevent or resist the tendency to loose the fastenin gs of the gudgeons, whereby a wabbling unsteady motion would be given to the main roller C, thereby materially impairing, if not quite destroying, its utility, and consequently that of the machine. vThe gudgeons c c, flanges b b, and elongations b b being of one piece and solid, may be manufactured of any suitable `cheap metal. The length of the wooden center piece c is somewhat shorter (d", Fig. 10) than the surrounding rubber c c, so that the rubber c c is horizontally compressed, when the metal flanges b b are rmly fastened to the ends of the wooden center piece c' 0'., whereby the full power of the elastic ilexible nature of the said rubber is obtained. Said center piece may be iiuted or diamond-shaped on the surface covered by the rubber, to prevent the rubber from sliding. E E, Figs. 3, 6, and

7, are two sliding met-al boxes about six inches v long, two inches thick, and four inches wide,

ing the expense as well as the inconvenience of two mach1nes;. or, by the simplest conversion, making one machine do the work of two.

, Claim.

I claim- The main roller C and small rollers G Gr G', as constructed, acting upon each other, as specified, in combination with the metal sliding boxes E E, rubber springs E E, meta-l staples or strrups F F,thu1nbscrews f f', metal concave frames or ribs H H, rubber springs or cushions h" h, and end boards I I, embodying the construction of va machine whose action shall be vertical and uniform, however the power may be applied, as and for the purpose specified.
